Membrane protein thermal stability assays

CALIXAR proposes Thermal Stability Assays to get information about expression levels, stability and ligand binding of membrane proteins. The Andromeda system (Nanotemper) gives protein thermal unfolding data to help scientists to define optimal expression conditions that ensure the highest expression level together with the best thermal stability of membrane proteins.

Protein Characterization with Thermal Stability Assays

Access to the latest technology of Thermal Stability Assays using Andromeda system (Nanotemper).

Andromeda measures the thermal unfolding of a protein by detecting changes in fluorescence during a thermal ramp.
